Approximately how many grams steam are formed from 25grams of water?
25 grams of steam are in 25 grams of water.
How many moles are present in 500.00 g of H2O?
For this you need the atomic (molecular) mass of H2O. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. H2O= 18.0 grams500.0 grams H2O / (18.0 grams) = 27.8 moles H2O
What is water mass?
What is water mass?depends on the volume of water but one molecule should be about ahhh lets seemolecules are measured in Atomic Mass Units (amu)hydrogen is 1 amu and oxygen is 16 amu so..h20 =h * 1 amu * 2 molecules= 2o * 16 amu * 1 molecule = 162 + 16 = 18 amu or 18 grams/ mol
Waters high specific heat is mainly a consequence of?
Water has a high specific heat capacity because it is a relatively light molecule (18 grams per mole). The specific heats of molecules are all about the same on a per-molecule basis, especially at higher temperatures. This is called the law of Dulong and Petit. At low temperatures, it gets more complicated because the vibrations of molecules are quantized. When specific heats are measured on a per-gram basis, lighter molecules have higher specific heats. For example, the specific heat of hydrogen (H2), which has a molecular weight of 2 grams per mole, is much higher than that of water. Liquid water has a higher specific heat than most other liquids (such as alcohols) because its molecules are lighter.
How many ounces in 18 baguette slices?
A French baguette can range between 200 to 300 grams depending on the region. A normal baguette (at 250 grams) is 8.8 ounces.
How do you determine the number of molecules of water you swallow from a cup of water?
A cup is 8 fluid ounces. And 8 ounces is about 236.6 grams of water.There are 18 grams of water in one mole of water, and a mole of anything contains Avogadro's number of molecules of that compound. That's 6.02 x 1023 molecules.Our (236.6 grams of water) divided by (18 grams per mole) = 13.14 moles of waterOur (13.14 moles of water)(6.02 x 1023 molecules per mole) = 7.91 x 1024 molecules in the 8 ounce glass of water.We had 8 ounces of water. We converted to grams. Then we looked up water to see how many grams of water there were in a mole of water. Then we found out how many moles we had in our cup of water. Then, because we knew how many molecules of water were in a mole (we know because a mole of anything is Avogadro's number of particles of that substance), we multiply to find out how many molecules of water were in the cup of water.That's how we found that there are 7.91 x 1024 molecules in a cup of water.
How many molecules are in 10 grams?
A mole of water is about 18 grams or 18 milliliters of water.A mole of water has 6.022 x 10^23 water molecules. And 10.0 grams of has 3.345 × 10^23 water molecules. And there are 3 total atoms in water molecules, which is H2O. (3.34 × 10^23)*3=1.006 × 10^24 Which means that 1x10^24 atoms are in 10.0 grams of water.
How many molecules are in 4.21 grams of water?
45 grams H20 x (1 mole H20/18 grams H2O) x (6.02E23 molecules H20/1 mole H2O) the grams H2O and moles H2O cancel out. When you punch it into your calculator, the answer comes out to: =1.505E24 molecules H2O
How many teaspoon in 90 grams?
90 grams of water is approximately 18 teaspoons.
How many molecules are there in 12 grams of ice?
Weigh the ice cube (Let's say it weighs 36 grams, about an ounce) The weight of 1 mole of water is 18 grams 1 mole of anything contains 6.022 x 1023 molecules In our example: 36 grams of water contains 36/18=2 moles of water 2 moles of water contains 2x 6.022 x 1023 = 12.044 x 1023 molecules
How many grams of oxygen are contained in 18g of water?
The molar mass of water(H2O)=18((1*2)+16)The no. of moles(n) of water in 18 g of water=mass/molar mass=18 g/ 18 g mol-1 =1 molThe no. of molecules of water in 18 of water=n*Avogadro no. =1 mol*6.022*1023 mol-1 =6.022*1023The no. of atoms of oxygen in one mole of water=1 molThe no. of atoms of oxygen in 6.022*1023mol of water= 6.022*1023
How many molecules of H2O are there in 3 grams of H2O?
The molecular mass of H2O is 2(1.0) + 16.0 = 18.0Amount of H2O = 3/18.0 = 0.167mol The Avogadro's number is 6.02 x 10^23 Number of molecules of H2O in 3g sample = 0.167 x 6.02 x 10^23 = 1.00 x 10^23
How many molecules in 1kg of water?
Hi, You need to work out how many moles of water you have in 1L of water. Then you need to know that the Avrogadro constant is the number of molecules on a mole of anything. so; water = H2O Atomic weights: Hydrogen = 1 Oxygen = 16 Mole weight of water therfore; 18 grams 1L water = 1000 grams avrogadros constant is 6.0221415 x 10^23 :. 1000 /18 = 55.5555' moles water 55.5555' x Avrogadros const = 33456308210325000000000000 = 3.3456 x10 ^25 molecules of water. Please check my figures - I don't have a scientific calculator handy. Hope this helps, Mike.
